Peonia is a character first introduced in "The Crown Tundra" DLC of "Pokémon Sword and Pokémon Shield". She is the older daughter of Peony, her younger sister being Penny, and is going through her rebellious teenage phase, hating all the things her dad tries to do to impress her, such as her "Adven-tours". The player, Victor or Gloria, can go on Dynamax Adventures with her together.

Due to her relation to Peony, she is also the niece of Rose.
